<p>PURPOSE:To prevent slip in an electromagnetic clutch of a compressor by controlling power supply to the electromagnetic clutch and a blower motor if the voltage applied to the clutch has sunk. CONSTITUTION:Electromagnetic clutch 10 of a compressor 4 is connected with a voltage sensor 18, and a voltage level judging means 23 is connected with the output side of this voltage sensor 18. The output of said voltage level judging means 23 is connected with a control means 17 to control power supply to the motor 2a of a blower 2. Thereby power supply to the electromagnetic clutch 10 and blower motor 2a can be controlled properly according to voltage drop even when the voltage applied to the clutch 10 has sunk. Thus slip in the clutch 10 can be well prevented.</p> |
